CAR -NIOVER.

SPECIFICATION forming part of Letters Patent No. 397,911, dated February 19, 1889.

Application filed May 21, 1888- Serial No. 274,523. (No model.)

T0 (0 whom it may concern.-

Be it known that I, JOSEPH P. HALPIN, a citizen of the United States, residing at yandotte, in the county of IVayne and State of Michigan, have invented certain new and useful Improvements in Car-Movers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in car-movers; and the invention consists in the novel construction and operation of a gripper-wheel and in the general arrangement and combination of different parts, all as more fully hereinafter described.

In the drawings which accompany this specification, Figure 1 is a side elevation showing my improved car-mover as in operation. Fig. 2 is an end elevation of my car-mover, and Fig. 3 is a cross-section of the gripper wheel.

A is a suitable frame to support the operating parts.

B is a gripper-wheel journaled in the lower end of the frame, and this wheel is provided with a groove, 0, around its periphery, which is of such size in cross-section that it will allow the wheel to clamp or grip upon the side of the head of a rail.

For the purpose of effecting a strong grip or frictional contact between the grippingwheel and the rail I preferably construct the wheel of cast steel'or iron, with the grippingface thereof serrated, ribbed, file-cut, or otherwise indented or roughened to bite the rail; but any other construction of wheel to obtain the same object of gripping the rail may be employed.

D are sprocket-wheels secured to the sides of the gripper-wheel or integrally formed therewith.

E is a shaft journaled near the upper end of the frame, and provided with the sprocketpinions F and cranks G, for imparting n10- tion thereto.

H are sprocket-chains for conveying 1110- tion from the shaft E to the gripper-wheel.

it to turn and advance 011 the rail, exercising 6 Oi thereby a lifting and pushing power sufficient to move several loaded cars.

By means of the extension shoulder-piece the device is adjusted for higher or lower cars, so as to give it the suitable inclination to transmit power in a forward direction without allowing the gripper-wheel. to slip. In stead of the crank and sprocket-chain gearing any other hand-motor device may be used to rotate the gripper-wheel.

Importance is attached to the peculiar construction of the gripper-wheel with. sprocketteeth on each side of the groove, whereby I obtain greater power and am enabled to place the chains on the outside instead of the grooves, as heretofore.

\Vhat I claim as my invention is- In a car-mover, a gripper-wheel formed with circumferential groove having inclined gripping-walls, and with sprocket-teeth upon each side of said groove, substantially as and for the purpose specified.

In testimony whereof I aliix my signature, in presence of two witnesses, this 27th day of April, 1888.

JOSEPH P. HALPIN.
